Description

To decide what HS statistics projects to do for SponsorR, we've been following the approach:think of all statistics we could collect and decide whether we should or not do them. This approach has lead to various confusions on whether a statistic is useful to us or not.

To make it easier to reason about the usefulness of statistics, we decided to take a different approach which is Enumerate useful research questions we want to answer, and collect statistics that could help us answer them.

Such research questions could be:

Is 6 HSDirs the best number of HSDirs?

How long should HSDirs cache descriptors?

Are IPs stable or are they subject to churn? How often do HSes change IPs?
